Abstract: A method for dynamically generating rules for an enterprise intrusion detection system comprises receiving a packet flow from a sensor. The packet flow is dynamically processed to detect if the packet flow represents an attack on the enterprise system. A response message is automatically generated in response to the attack, the response message comprising a signature to identify the attack. The response message is automatically communicated to a response message file, the response message file comprising at least one response message.

Abstract: A method for vertically extensible intrusion detection for an enterprise comprises receiving a first packet flow from a first node, the first packet flow comprising at least a portion of packet headers received at the first node during a first timeframe and receiving a second packet flow, the second packet flow comprising at least a portion of packet headers received at the second node during a second timeframe. The first and second packet flow are processed to detect an attack on the enterprise system. In response to the attack, an alert message is communicated to a master server, a response message is received from the master server, the response message comprising a signature to impede the attack, and the response message is automatically communicated to the first node and the second node.

Abstract: A method for interfacing with a user of an enterprise intrusion detection system, the method comprises receiving at least one packet flow, each packet flow originating from a unique node in the intrusion detection system and comprising descriptive information and a plurality of packet headers. The descriptive information of a first subset of the received packet flows is communicated to a user based at least in part on a filtering ruleset. A second subset of the received packet flows is concealed from the user based at least in part on the filtering ruleset. In response to receiving a command from the user, the plurality of packet headers for at least one packet flow in the first subset is communicated to the user.
